Application and June 9, 1913. serial No. 772,463.

To all whom it may conf-ern Beit known that I, CHESTER H. BEACH, acitizen of the United States, and resident of Racine, in the county ofRacine and State of Wisconsin, have invented certain new and usefulImprovements in Vacuum-Cleaners; and l do hereby declare that thefollowing is a full, clear, and exact description thereof.

My invention has for its object to provide a simple, economical andlight-weight vacuum cleaner of miniature type for hand use, the samebeing particularly designed Vto take the place of whisk-brooms oranalogous devices for cleaning clothing, or'various articles notincluding floors" or carpets, as, for example, the felt surfaces of gametables, and to meet the various requirements as to the scope of thecleaner I also provide certain detachable members that can readily beinterchanged by the user.

With the above objects in view the invention consists in what is lhereinshown, described and claimed.

In the drawings Figure 1 represents a side elevation of a vacuunrcleanerembodying the features of my invention, parts of the machine beingbroken away and in section to more clearly illustrate structuralfeatures, which sectioned parts are indicated by line 1 -71 of Fig. 2,and Fig. 2, an inverted sectional plan view of the same, the sectionbeing indicated by line 2 2 of Fig. 1.

Referring by characters to the drawings, 1 represents a housingcontaining an electric motor 2, the said housing being provided with agrip-handle' 3 having a tubular stem 3' that. carries the usualfeed-wires 4 for, supplying energy to the motor. lThe shaft 2 ot themotor projects through the lower face of the housing and also through aneccentrica'lly disposed boss 5 of a circular casing 5, 'the same beingin the form of an inverted cup having its lbottom wall secured to thelower face of said housing by bolts 6. The bolts pass through aperturesini the housing and engage feet 6', the same being secured to the bottomwall 5" of the cup-like housing by screws as shown. The mouth of thecasing is provided' with an inturned lip 5"', which lip extends aroundthe casing edge being concentric with the motor axis, and` forms an airintake opemng. The casing 1s also provided with an air discharge nozzle5"", which nozzle extends at a tangent to the side wall of the casing. Y

'operatorV or others.

Fitted over the casing boss 5 isa cupped hub 7, a flange of which hubcarries a fan `latentes apr. 21,1914.

disk S'that. has secured toits lower face a l series of 'depending vanes9, the disk and Yanes constituting a fan, The hub 7 of the fan issecured to an extension of the motershaft 2' by set-screws and isprovided with a reduced shaft-extension 7';

Loosely mounted upon the shaft etxension T' is a spider 10, the arms ofwhich spider constitute heads for depending brushes 10' the working orbrushing `faces of whichbrushes vnormallyV project slightly below theplane of the casing mouth. The br'ush spider is capa-ble etAlongitudinal yield in opposition to tension of acoiled'spring 11 thatsurrounds the shaft extension 7 the said Spring being interposed betweenashoulder ofthe fan hub and upper face of the spider, whereby saidspider is seatedagainst the flanged head, of a set-screw 12, whichset-screw is in threaded union with-the motorshaft extension. Thusbyadjusting the set-screw 12 the working or brushing face of the brushlnay be regulated with rel-ation to the mouth of the fan-casing.

The discharge nozzle 5" has detachably secured thereto a thimble 13, thethimble forming a rigid receiving mouth for a p01- `ous dust-collectingsack 14, which is attached thereto. The opposite end ofthe sack orseparator is left open for the purpose of emptying the deposits of dustthat may accumulate therein and vin its operating position the open endis closed by a: spring-clip 15, which clip is suspended from a'hook thatextends from the handle stein 3.

In the operation of the cleaner as exemplitied above, the operatorgra-spe the machine in one hand and directs the same over the surface orclothing either of the Current being supplied to thev motor, it isapparent that the fan will be rotated and its vanes which projectbetweenthe spider arms will cause simultaneous rotation of the brush, Theflanged mouth of the fan casing in the meantime .is slowly moved overthe surface to be cleaned. ThusF the dust, is positively loosened fromthe fabric -and coincident thereto the partial vacuum producedcauses thedust-laden air to be drawn into the casing and discharged therefrom intothe separater sack, from which point the air is exhausted to atmospherethrough the pores of the latter. 4It is also obvious that in operationthe brush bristles are pressed into contact with the surface to becleaned'by lthe coiled spring 11, the said lbrush being capable ofslight rise and fall as it follows the contour of the surface over whichthe shellmouth travels. The cleaner may also be utilized for variousother` purposes wherein it is desirable` to rst subject the material toav positive brushing operation,

as, for example, it may b e utilized for cleaning animals or varioussurfaces where hand manipulation is desirable. It is also apparent vthatby the peculiar attachment of the spider brush in connection with thefan, as shown in Figs. l and 2 of the drawings, said brush vcanbereadily removed when it is desired to utilize the machine as a.suction cleaner only and that the pressure of the brush can be regulatedby adjusting said brush up or down.

I claim:

1. A vacuum cleaner comprising a housing having a handle extendedtherefrom, a motor mounted within the housing havingashaft extension, aninverted cup-like casing secured to one face of the housing throughwhich the shaft extensionl protrudes, a brush-carrying spider` mountedupon the shaft extension and revoluble therewith, and means forpermitting longitudinal yield of the spider upon said shaft extension.

2. A vacuum cleaner comprisin a housing having a handle extending terefrom, a motor mounted within the housing having a shaft extension, aninverted cup-like casing secured. to one face vof the housing throughwhich the, shaft extension protrudes, a fan secured to the shaftextension-having vanes extending downwardly, a spider loosely mountedupon the shaft extension, the spider being disposed in the path oftravel of the fan vanes, bristles extending from the spider having theirbrushi ing ends normally exposed slightly below the plane of the mouthof the easing, and a coiled spring surrounding theshaft extensionadapted to exert pressure against the spider.

3. A vacuum cleaner comprising a housing having a handle extensiontherefrom,

.a motor mounted within the housing hav- `ing a shaft extension, aninverted cup-like casing secured to one face of the housing throughwhich the shaft extension protrudes, afan secured to said shaftextension having vanes extending downwardly, a spider mounted upon theshaft extension, means for causing the spider to revolve with the shaft,bristles carried by said spider, a coiled spring surrounding the shaftexten- .sion adaptedrto exert downward pressure upon the spider, andadjustable means carried by the aforesaid shaft extension for limitingmovement of said spider.

4. A vacuum cleaner comprising,l a housing having a handle extendingtherefrom,V a motor mounted within the housing having a shaft extension,an inverted cup-like casing-depending from the housing through which theshaft extension protrudes, a fan secured to the shaft extension havingvanes extending downwardly, a spider loosely mounted upon the shaftextension, the spider being disposedin the path of travel of the fanvanes, bristles extending from the spider having their brushing endsnormally exposed shghtly below the plane of the mouth of the casing, anda spring carried by the aforesaid shaft extension adapted to exertpressure upon the spider.

In testimony that I claim the foregoing I have hereunto set my hand atRacine in the county of Racine and State, of Wisconsin in the presenceof two witnesses.
